A batch is one transaction, so every page it copies now draws on one
budget: two large copies can no longer push the batch past Convex's
limits, where it would fail, and fail again on every retry. A lineup
image several pages show is charged to a copy once, as it is copied
once, so "Duplicate strategy" refuses no strategy it accepted before.
